Lightest 18350 flashlight?

As you mention……
The weight is not 40 grams,
the correct weight is 52.
I was not anywhere near a scale, relying instead on the weight specified by Illumination Supply, where I purchased my light.

Except that it runs on 16340, not 18350.

Any idea on the actual weight?

Thanks!

On AliExpress you can find super cheap (<$2) skywolfeye flashlights that use 18650s, they have wall’s thin like soda cans, possibly fake or super old cree emitters, but I can’t really recommend them

S2+ with shorty tube and TIR?

Anyone ever weigh that?

MascaratumB weighed it at 86g, I believe.

It runs on both batteries.
If you look at the specifications and battery sizes, you will see 18350 is included, simply not mentioned in the title.

I did here: Convoy S2+ Desert Tan Available Now! - #1245 by MascaratumB

Although it has the reflector and not the TIR, that wouldn’t make the difference in this case.
The final weight with battery is above 86g (with a Keeppower battery, that is lighter than an Aspire), meaning that only the body of the light will weigh more than 60g. And that was the limit asked by Pete.

EDIT: BTW, has anyone ever seen this light/project ? I guess it ended in “nothing”, but this was a pretty light (and they had others) :heart_eyes:
It was from “helioslight”, and I guess this is not the actual “Heliuslight” (it has some posts and threads here on BLF)

Hmm. Figured with plastic TIR vs Al reflector, might lighten it up a bit.

Use a lighter cell? :smiley:

Why the 60g limit, though?

Sorry, I have no scale available.
With 18650 tube it’s 66 grams (+ cell).

Anything more than this, and it becomes impractical when attached to a cap visor for extended walking, in my experience. And I would like more runtime than what a typical 16340 cell allows. 2 hours of runtime at about 300 lumen output would be nice.

I don’t want to use a head strap.

maybe try clipping a raw 18350 to the hat, something tells me the cell alone may also be too heavy…

i don;t think i would like anything over 30 grams for that

maybe you have a different kind of hat

there are also ‘headlamps’, some of them might be adaptable to cap wear
they may, but not always, have batteries via wire, making the head part lighter but adding the annoyance of a wire

56.2g with 18350 tube.
69.1g with 18650 tube.

grey 18350 tube 14.28g

Slight weight variations in my different emitter models and tubes, batteries.
Not sure what the lightest battery would be. Most are listed with ‘in the ballpark’ weights in their specs.

If you use a shorter brim hat, the extra 19g over your spec of 60g weight wont be so bad…? So, don’t be a flat brimmer… lol

Thanks. Based on what was posted above, Aspire 18350 weighs 25g, so that means a D4 with 18350 battery would come in at 81g.

LOL!
Interesting suggestion though. I wasn’t aware that baseball caps come with longer and shorter visors. I’ll have to look into this.

As for the D4 specifically, my main issue with it is the ramping UI. I’d much prefer something that has preset output levels, so that you can gauge battery runtime better.

Yes, my aspire is 25, or more precisely, 24.8. My lightest 18350 is 23g… so that puts it at 79g with my lightest 18350

Here is my setup, I don’t find it uncomfortable at all. Can ramp to the perfect brightness level with a simple hold of the button. For me, ramping headlight, its the perfect setup. At full regulated level the light will go for many many hours and at that level on a dark pathway, seems to be enough light for me. If I need lots more then 2 fast bumps on the button puts out over 4000 lumen. Raccoons run for cover with bleeding eyes…

Jaxman E2L with 18350 tube + Aspire 18350-cell:

More than 60 gr but still pretty lightweight.

allcool, how long is the brim on that hat? I just ordered a hat with a 2” brim to try. I’m pretty sure my current hat has a longer brim, but I’m out of town, so I can’t verify.

my brim might be longer then yours, but by no means is it flat… lol

Thanks. Also, what clip are you using with that D4 shorty?
